This invention relates to a storm window sash adjuster which containsmany new features of design, and consequently offers advantages andimprovements not heretofore found in such devices. This invention hasfor one of its principal objects to provide an adjuster which mayeasily, quickly, and without the aid of any tools be connected ordisconnected from the storm sash. Thi we have accomplished in a new andunusual manner.

Other objects are to provide an adjuster which will also serve to lockthe storm sash securely in a closed position, and to provide meanswhereby the adjuster will remain in any desired position.

Further objects such as simplicity, strength, durability, low cost,etc., will appear from the following description and drawings whereinFigure 1 is a perspective view of our sash adjuster in a partiallyopened position, shown attached to a window frame and storm sash;

Fig. 2 is a side elevation of the adjuster in the position which isreached just prior to its disconnection from the sash;

Fig. 9 is a top plan view of the adjuster shown in Fig. 8.

Our new and improved window sash adjuster is in the form of a linkcomprising arms A and B made of metal or other suitable material. Arm Ais formed with a long side wall I5, a short side wall I6 parallel withand opposed to the wall I5 and a connecting bottom I! which terminatesshort of the ends of the wall I6. A channel that normally faces upwardlyis thereby provided. The long side wall I5 is offset at I8 as shown inFig. 4. Arm B may be made of flat stock as Shown in Fig. 4, or of roundheavy wire stock as shown in Figs. 8 and 9. This arm is formed with anelongated hook I9 at its outer end and a stake 2 Claims. (Cl. 292-263)20 outstanding from the arm about opposite the hook and forming ashoulder.

Arms A and B are pivotally joined as by means of a nut and bolt 2|. Inthis assembly the arm B is sandwiched in between the walls l5 and I6 ofthe arm A and is separated therefrom by friction washers 22 (see Fig. 2)which are positioned wholly to the inside of the walls I5 and I6.

When .inuse the inner offset end of arm A is pivotally secured to theframe 23 of a window as by means of a screw or bolt 24, and the outerend of arm B is secured to the sash 25 of the storm window by insertingthe hook I9 into an A eye fitting 26 of the ordinary common type which15 may be attached in the usual manner to the storm-sash. This is doneby merely swinging the pivotally joined ends of the two arms A andB'upwardly to a near top position, as shown in Fig. 2, and then feedingthe hook into the eye. This is possible due to the absence of any bottomor stop on arm A in the region of the pivot bolt ZI which allows the armB to be swung through more than 270 until it fetches up against upagainst the bottom Ii. By reversely swinging the arms to thestraight-line position (see Fig. 3) or further, the hook I9 is securedin the eye 26 and cannot be removed. To disconnect the hook I9 from theeye 25 it is merely necessary to swing the arms upwardly to a point wellabove the straight-line position (see Fig. 2) whereupon the link may bemanipulated to effect the desired release.

To adjust the storm sash inwardly the arms are swung downwardly as shownin Fig. 5, and when fully closed the arms will be in the position shownin Fig. 6. The stake 20 prevents the hook I9 from riding up into the eye26 when the links A and B are in a swung-down position (see Figs. 5 and6) When the storm sash is fully closed, as in Fig. 6, it may bepositively locked in such position by rotating the closed arms A and Bupwardly 180 (see Fig. 7) from the normal closed position of the linkshown in Fig. 6. The arm B is then prevented from opening outwardly bythe bottom I! of the arm A against which it rests. To release the armsfrom this locked position it is necessary merely to rotate the armsdownwardly away from the storm sash to the position shown in Fig. 6.

The friction washers 22 when compressed by properly adjusting the bolt2| serve to adequately hold the link in any desired position, thusproviding the widest possible range of adjustment of the storm sashinwardly and outwardly.
